く損なう欠点をもっていた。A web obtained by thermocompression-bonding a dry nonwoven fabric or a wet nonwoven fabric made of aramid fiber and unstretched polyester fiber with a calender roll is considered to be most suitable for this application. Due to the occurrence of the wearing, the sheet is fluffed, and the sheet is easily cut based on the roller being taken off. Therefore, the calendering speed has to be reduced to an extremely low speed, which has a disadvantage that productivity of the web is significantly impaired.

ましくない。In general, the fineness of the single yarn is preferably small because a flexible web can be obtained. In view of industrial applicability, the single-fiber fineness is generally preferably 0.5 to 4.0 denier. Fibers smaller than 0.5 denier are not practical because of poor productivity. If the denier exceeds 4.0 denier, the web becomes hard and the roller is liable to be worn. In addition, the number of fibers constituting the web is reduced, so that the cleaning property is poor.
【００１２】本発明においてポリエステル繊維の好まし

It is desirable to keep 335 to 1.350. 1.335
Unstretched yarns having a specific gravity of less than 10 are practically problematic because of their difficulty in industrial production, and exceeding the upper limit is not preferred because thermal adhesion is impaired.

構成繊維の本数が減り接着性を損うので好ましくない。A preferable range of the single-filament fineness of the undrawn polyester fiber is 0.8 to 6.0 denier. Undrawn polyester fibers of less than 0.8 denier are expensive due to the difficulty of industrial production. If it exceeds 6.0 denier, the number of fibers constituting the web is reduced, and the adhesiveness is impaired.

The specific gravity measured by the method described below must be in the range of 1.38 to 1.41. A drawn yarn having a specific gravity of less than 1.38 cannot prevent hot roll fusion of an undrawn yarn even if coexisting. A drawn yarn having a specific gravity exceeding 1.41 is not preferred because it is difficult to produce industrially and the flexibility of the web is impaired.
